Out of sight: A lateral geniculate body hemorrhage hidden behind hemianopia – A rare presentation

This case report describes a case of sudden onset isolated visual field defect as a presentation of hypertensive thalamic hemorrhage in a 47-year man with poorly controlled hypertension. Neurological examination revealed a left homonymous hemianopia and neuroimaging demonstrated an acute hemorrhage involving the right lateral geniculate body and optic radiation. The lateral geniculate body, a thalamic relay nucleus, plays a role in visual processing, and isolated involvement rarely produces pure visual field deficits. This case highlights, hypertension related lateral geniculate body hemorrhage as a rare but important cause of isolated homonymous hemianopia and underscores the need for prompt neuroimaging and management.
